I see a lot of unofficial anime-style Touhou opening and ending videos with something like "Touhou Anime Kinema-kan" mentioned in the title or description. For example:
- Touhou Anime Motion Picture ~Second Curtain~ 2nd PV 【東方】
- Touhou Hana Kagura【Anime Motion Picture 2nd Curtain #2】【東方】【HQ】
- Touhou Anime Kinema-kan - "東方白昼夢" ToHo Daydream(FULL)
But I can't find a good description or explanation of what exactly Touhou Anime Kinema-kan is. What does Kinema-kan mean? What does it refer to? And what does 2nd Curtain refer to? Is there a 1st Curtain, 3rd Curtain, and so on?
All I can gleam from the video descriptions is that it seems to be something that was released at Comiket or Reitaisai, but I don't know much beyond that.
